Need Some Help Narrowing Down Your Options? Here's Some Additional Information to Consider:
Figure Out Which Mattress Will Best Suit Your Needs
Firm Mattresses

If you want a firm mattress, a Serta king-size mattress might be a good choice for you. Firm mattresses offer proper weight distribution, supporting your back and other sensitive areas. Providing improved circulation, they promote deeper sleep. They are ideal for those who sleep on their back and have a 34-36 pound indentation load deflection rating. A potential downside is that firm mattresses can put strain on specific pressure points, including the shoulders and hips. Also, they might be uncomfortable if you're not used to sleeping on hard surfaces, so it can take some time to get used to them.

Plush Mattresses

Are you searching for a plush mattress? Take a look at a Serta king-size mattress. Plush mattresses give you extra support to ease any back problems or joint pain that you're experiencing. They have a 19-21 pound indentation load deflection ranking and are suitable for those who tend to sleep on their back, sides, or stomach. These contouring support mattresses adjust to your body shape for optimal comfort. One downside is that they may be problematic if different sleepers will be using the bed, causing the surface to sag if there is a drastic difference in weight. In addition, they are more likely to become a bit lumpy or sink in over time, so your body won't be properly supported while sleeping.

All You Need to Know About Mattress Thickness
8-10 Inch Mattresses

Looking for a Serta king-size mattress that's not too thin or thick? There are two for you to take a look at. These mattresses have a standard thickness, so you can rest assured knowing that they'll be able to fit in nearly all bed frames. They are suitable to use with standard-size sheets, so it will be easy to find linens that fit. They are less likely to cave in, so the surface will remain level to ensure proper support over time. Something to keep in mind is that they tend to wear out quickly, so they won't last long before beginning to deteriorate. Additionally, they can get indentations if there's too much weight put on them, so if you're looking for a mattress for a couple, they're not a great choice for you. If you think an 8-10 inch mattress is a good choice, here's one to take a look at.

10-12 Inch Mattresses

They are suitable to use with standard-size sheets, so it will be easy to find linens that fit. They are less likely to sag, so the surface will remain flat to ensure adequate support. One downside is that they feature a heavier design, which makes cleaning difficult because two people are required in order to move them. These are just a few facts to help you decide what kind of Serta king-size mattress you need.

12-14 Inch Mattresses
